./configure --localstatedir=/wherever (defaults to /var or ${prefix}/var)

That will change everything that normally is placed or looked for under
/var (/var/lib/pacemaker, /var/lib/heartbeat, /var/run, etc.).

Note that while ./configure lets you change the location of nearly
everything, /usr/lib/ocf/resource.d is an exception, because it is
specified in the OCF standard.
